I describe the pinout to make it yourself here:

Thanks for the pinouts, but don't they show a null modem cable? I am trying to a straight forward serial cable, one that I would connect to a modem, or in my case a Terminal Node Connector, a radio modem.

Sorry, yes - going directly to a modem or similar, you don't need null-ness. So yes, a MiniDIN8 to DB25 Mac Modem cable is exactly what you need. I see one on Amazon:
